About: Marshall Bromley 750 Bluetooth Wireless Party Speaker - Black / Brass

Make the street, forest, or garden your venue as this powerful portable speaker can play free from wires for 40+ hours without taking a breath. You’ll never miss a bass drop, as its True Stereophonic360° sound can reach wherever you’re standing, even outdoors. Bromley 750 has been tuned for all volumes, and makes a heavy statement wherever it shows up.

True Stereophonic 360° Sound

Feel every detail no matter the volume thanks to 360° sound that wraps you up. Crystal-clear sound hits every corner and finds its way through any crowd. In a warehouse or a field, there’s nowhere to hide.

Adjust Your Party Sound

Move between pre, peak and after party to discover how the sound character control knob’s “Dynamic” to “Loud” scale can tailor sound for laidback and high-energy listening moments.
For the best listening experience, use headphones.

40+ Hours of Portable Playtime

When power runs low, replace with a backup battery, or use the AC cable to plug in. Take your party through the night and onto the next, with track one sounding just as good as your final outro.

Take A Closer Look

Bromley 750 delivers a fully immersive and dynamic sound performance. Engineered with True Stereophonic, a unique form of multi-directional sound, music fills the air above and around you. Its durable, closed-box design ensures a tighter, more controlled, and natural sounding bass.

Side-Firing Drivers

Two side-firing drivers help create 360° sound that you can hear from all angles.

Top Tweeters

Up-firing tweeters expand Bromley 750's sound performance by pushing out audio over your head, and fully immersing you.

Front-Firing Drivers

A powerful front-firing driver and tweeter deliver sound you can truly feel. The grill and lights have also been precisely placed so that they don't affect acoustics.

Rear-Firing Drivers

Rear-firing drivers complete Bromley 750's sound design to ensure you can hear the music no matter where you're standing. The rear-facing cone is also attached to the tweeter to amplify its sound.

Sound Character Control

Match your music to the pace of your party with a few simple adjustments. Select ‘Loud’ for full power in a large space or ‘Dynamic’ for a more laid-back setting.

Integrated Stage Lights

Light up the room with stage-inspired lights that synchronise to fit the mood. Pick from three presets on the speaker that each put on their own unforgettable show.

Mic & Instrument Inputs

Connect to mics, instruments, and turntables for the ultimate party. Play with audio effects to switch up who gets the limelight or keep everything in balance with simple adjustments on the control panel.

Dirt & Splash Resistant

Start the party inside then head out. Its IP54 rating and built-in drainage system takes care of rain and dirt. Getting dusty between performances won’t affect it either.

Built-In Handle & Wheels

Start the party without an entourage. Bromley 750 is fully transportable thanks to its wheeled design and retractable handle. Tilt and use the wheels to roll it then use the side handles to lift it into place.
